A Clinical Evaluation of Implant-Supported Maxillary Obturator Prostheses

Abstract

Introduction: Rehabilitation after the maxillectomy is challenging to the clinician and the patient. Since the invention of the implants, the rehabilitation has changed the treatment strategies. Hence in our study, we evaluated the maxillary obturator that is implant supported. Materials and Methods: We piloted a retrospective analysis of the patients who received the maxillary obturator prosthesis with implant support from the department records from 2010 to 2020. We finalized 50 subjects who fit the criteria and evaluated clinically for various parameters. The comparison of these parameters was done using the Chi-square tests deliberating P < 0.05 as significant. Results: We observed that the implant survival was 94%. There was significant variation for the implant bone height ( P = 0.001) and the implant threads exposed ( P = 0.044) for the posterior and the anterior regions. Conclusion: The implant-supported maxillary obturator prosthesis has been shown to perform clinically satisfactorily. The success of the implant-supported maxillary obturator is dependent on the time of the placement, load applied, the radiation regime, and the patient follow-up.

Prosthetic rehabilitation of patients with maxillary oncology defects using zygomatic implants

“…Maxillectomy for malignancy often results in a maxillary defect and severe oral dysfunction [ 56 , 57 ]. The choice of method for surgical rehabilitation of patients after tumor resection depends on a number of key points, such as the patient’s age, the presence of concomitant pathology, size of the defect, as well as the professional skills of the surgeon [ 58 ]. Microsurgical reconstruction increases the duration of hospital treatment, morbidity in the donor area, and the incidence of complications in both the recipient and donor areas, and also limits the possibility of direct visual diagnosis of disease relapse [ 59 , 60 ].…”

Prosthetic Treatment of a Patient With Resection of the Hard Palate With an Obturator With a Silicone Base

“…The addition of silicon materials facilitated the placement in the defect and prevented the emergence of decubital injuries which is accepted to be their main advantages (Mishra, N. et al, 2010). Their use improved the hermetic seal between the oral and nasal cavity which, according to studies, is decisive for the restoration of eating and speech (Mandal, N. B. et al, 2022).…”

“…The main purpose of the treatment is hermetic sealing of the created defect, via which the free entry of food and liquids in the nasal cavity to be limited (Parthasarathy, N. et al, 2022). The fabrication of a stable prosthetic construction is an important condition for the successful restoration of eating and speech (Mandal, N. B. et al, 2022).…”
